Definitions
- the present invention relates to a puncture sealing agent used for sealing a hole of a punctured tire.
- a puncture sealing agent used for sealing a hole of a punctured tire.
- Various puncture sealants are known as a repair agent for sealing a site where puncture occurs when the puncture occurs (for example, see Patent Document 1). These are mainly
- a colloidal dispersion polymer (latex) in an aqueous medium for example, polyethylene-butadiene latex, polyvinyl acetate latex, acrylic copolymer latex, nitrile latex, polychloroprene latex and the like are used.
- a device equipped with a pressure-resistant container containing a puncturing agent containing a liquefied gas as a pressure source for example, a sprayer Cans are used.
- propane / butane mixed gas is mainly used as liquefied gas.
- fluorinated hydrocarbons may also be used.
- One end of the hose is connected to the spray can by an outlet valve, and a screw adapter for a tire valve is attached to the other end of the hose.
- a puncture sealant When a puncture occurs in the tire, the puncture sealant is blown from the spray can through the tire valve into the tire. At the same time, the tire pressure is refilled with fuel gas at a specific pressure at a different level depending on the amount of gas leakage. At this time, depending on the degree of damage, the tire travels several kilometers while spraying a puncture sealant inside to seal the damage.
- a puncturing agent is stored in a compression flask connected via a gupta to a tyre valve from which a valve material has been previously extracted. The sealant is blown into the tire by the compression action of the flask. After insertion of the valve insert, the tire is reinflated to a specific internal pressure with the help of a carbon dioxide cartridge.
- Spray cans containing a mixed gas of propane and butane as fuel gas cannot be used satisfactorily unless the temperature is reduced to about o ° c, depending on the mixing ratio.
- mixed gas of propane and butane is a combustible explosive. Fluorocarbon hydrocarbons have a negative impact on the environment. Also, all known fuel gases are available only in limited amounts when a puncture occurs.

- the puncture sealant may accidentally adhere to the hands, face, etc. of the worker when repairing a punctured tire, or a puncture sealant that has been scattered with gas may be used. If a person inhales, it may cause health problems due to allergic reactions.
- Natural rubber latex is used to ensure the stability of latex. Usually, ammonia is added as a pH adjuster to adjust the pH to about 9 to 10. For this reason, during puncture repair, a strong irritating odor is generated from the puncture sealant, and the working environment for workers is not good, which may adversely affect health.
- puncture sealants include (1) puncture hole sealability, (2) ease of injection (easy injection of puncture sealant from valves, etc.), and (3) some degree of antifreeze (low temperature (Do not freeze during use), (4) Separation stability, etc., which does not separate even after long-term storage, is required.
